BINDING POST. I

Application flled March 31, 1922. Serial No. 568, 308.

and industries for connecting up the termi-.

nals of an energized circuit and it has for its primary ob ect to provide a binding post characterized by a novel means for looking the terminal wire thereto.

Another object of this invention is to provide a binding post havinga terminal wire locking means which will not cut or injure said wire, while ensuring its secure .20 retention in place.

A further object of this inve ntion is to provide a binding post which may be used for temporarily connecting up a terminal wire for experimental or other analogous purpose; or, alternatively looking a terminal wire thereto.

With the foregoing and other objects in view as will be more apparent from the fol lowin description my invention consists essentially in providing a binding post with" a transverse bore at right angles to the wire receiving opening and in slidably mounting in said transverse bore a pin having a cutaway wedge-like portion for impingement 85 on the terminal wire, and in means for looking said pin against axial movement.

11 the further disclosure of the invention reference is to be had to the accompnaying sheet of explanatory drawings constituting a part of this specification, and in which like characters of reference designate the same or corresponding parts in all the views.

Figure 1 is an elevation of one embodiment of my novel form of binding post.

Figure 2 is a similar elevational view but taken at right angles to the preceding figure.

Figure 3 is a central vertical section taken through a slightly modified form of the binding post; an

Figure 4: is a top plan view of the same.

Referring more particularly to the views a base or the. like of appropriate material is characterized by the numeral 5 and to 6 which my novel binding post is tabs attached. The. said binding post comprises a cylindric or other a propriately CI'OSS sectioned body 6, the ower end whereof is axially bored at 7 to receive an attaching screw or the like 8 by means of whichthe post is securely held to or mounted on the ase 5. In Figures 1 and 2 I have indicated the body 6 as circular in cross-section, while in Figures 3 ands: the same is of rectangular cross-section; but it will be obvious that any other appropriately cross sectioned body may be employed.

he ordmary terminal wire receivin opening is designated by the numeral 9 an it will be observed and noted that said opening is diametrically disposed relative to the vertical axis of the body 6." At right angles to the aforesaid opening 9 I drill or otherwise form a transverse bore 10 and on an examination of Figures 2 and 3 it will be clearly seen that this bore 10 is positioned to traverse through 01' cut into the wire receiving opening 9. Slidably fitting the transverse bore 10 is a pin 11, the wall whereof is cut out Wedge-fashion as shown at 12 to a sufiicient extent so that when-the deepest portion 13 thereof is over the terminal wire 14, the latter may be freely passed into and out of-or through-the opening 9. Now it will be perfectly clear that the slidable pin 11 is first inserted in the transverse bore 10 before the terminal wire is passed throu h the opening 9, and on an examination 0 Figure 2'it will be apparent that when the said pin is moved to the left hand the deepest part 13 of the cut out or wedgelike recession 12 can be positioned over the terminal wire 14 and thereby rmit of its easy movement relative to the blnding post or body 6. On the other hand, the forcing of the pin 11 towards the right hand in the same ii re will result in the jamming of the wedgeike cut-out 12 on to the terminal wire 14 and its frictional retention in place relative to the binding post or body 6.

In order to provide an efi'ective and simple means for locking the in 11 and terminal wlre 14 firmly toget er I preferably screw thread the outer ends of said in 11 to receive lock nuts 15, 15 the bores w ereof are slightly countersunk at 16 so that when a nut 15 or 15' isscrewed home tight against the post or body 6 the outer end of the pin 11 may be hammered or expanded thereinto as shown at 17. This feature of the invention I deem of considerable importance where the post is subject to heavy vibration,-as on automobiles for instance-as an examination of Figure 3 more particularly will conmerous advantages and usages whereof will be self-evident without further explanation or description.

While there has been shown and described the best form of m invention at present known to me, it wi l be apparent the same is susceptible of minor detail changes in shape and disposition of the several parts,

and the right is hereby reserved to make wearer such changes and variations as fairly lie within the scope of the appended claim.

Having described my invention, what ll claim as new and desire to secure by Letters Patent is:

- As a new article of manufacture a terminal Wire holding and locking member for binding posts comprising a slidable pin for passage through a bore at right angles to and intersecting a wire receiving opening through the binding post, said slidable pin having an inclined notchedsout part in the wall thereof for frictional engagement upon a terminal wire when connected into the binding post, and nuts threaded on the outer ends of the aforesaid pin whereby the same may be locked immovably in the binding post.

In testimony whereof I a my signature.
